用钻孔注浆法加固涌砂坍塌地基

Borehole Grouting Method for Reinforcement of Sand Influxing and Caving Foundation

摘要:

基坑开挖后，造成地下砂层向坑内大量涌砂，致使周围建筑基础地基塌陷，用钻孔注浆法加固砂层、填砾埋管注浆法充填加固塌陷地基是一种行之有效的方法。

Abstract:

Foundation pit excavation causes large volume of sand to inlux subsurface into the pit,resultingin surroundig foundation ground caveng,An effective way is to stabilze the sand formation using boreholegrouting method,and fill and reinforce the caving foundation using packing and buried tube grouting method.
